How to Prevent Brain Lesions In some instances, certain brain lesions can be prevented, though not all types can be completely prevented. [emedicinehealth.com]

Measures such as neck compression (tourniquet) and volume loading can be helpful in preventing VAE. PEEP increases the risk of VAE. [openanesthesia.org]
